Definitions
- Evaluation device and method for evaluating at least one
- the invention relates to an evaluation device for at least one radar sensor and a radar device. Furthermore, the invention relates to a method for evaluating at least one radar sensor.
- DE 10 2016 221 947 A1 describes a radar sensor for motor vehicles for determining the respective vehicle environment.
- the invention provides an evaluation device for at least one radar sensor with the features of claim 1, a radar device with the features of claim 5 and a method for evaluating at least one radar sensor with the features of claim 7.
- the present invention creates possibilities for evaluating at least one radar sensor, the measuring cycles of which are each interrupted by an intervening pause time, with “uninterrupted observation” by means of the present invention despite the observance of the pause times
- the present invention therefore brings about an improved Doppler resolution and a higher signal-to-noise ratio / signal-background ratio (signal noise ratio, SNR) when evaluating the at least one radar sensor. This also results in an increased sensitivity and / or a greater range when evaluating the at least one radar sensor by means of the present invention.
- SNR signal noise ratio
- Electronic device designed to carry out the Fourier transformation with respect to a Doppler effect-relevant variable using the measurement signals from at least two different measurement cycles and / or using the evaluation signals derived from the measurement signals from at least two different measurement cycles.
- the embodiment of the evaluation device described here therefore enables an improvement in the Doppler separability when evaluating the at least one radar sensor.
- the electronic device is preferably designed to perform a Fourier transformation with respect to a baseband frequency for each chirp of the at least two different measurement cycles and in this way to define a plurality of Fourier rows for each measurement cycle of the at least two different measurement cycles, and that using the perform Fourier transforms derived from the measurement signals from at least two different measurement cycles using the plurality of Fourier series of the at least two different measurement cycles and / or using evaluation signals derived from the plurality of Fourier series of the at least two different measurement cycles.
- the embodiment of the evaluation device described here can thus be easily used for a chirp sequence method.
- the electronic device is preferably designed to carry out a further Fourier transformation with respect to a Doppler frequency for each measuring cycle of the at least two different measuring cycles, using the plurality of Fourier rows defined for the respective measuring cycle, and in this way a two-dimensional Fourier series. Specify the array for the respective measurement cycle, and execute the Fourier transformation using the evaluation signals derived from the measurement signals from at least two different measurement cycles using the 2-dimensional Fourier arrays of the at least two different measurement cycles.
- the evaluation device is thus designed to add a so-called third dimension to an evaluation of the at least one radar sensor that is implemented by means of the Fourier transformations carried out first, in order to define the 2-dimensional Fourier arrays for all measurement cycles of the at least one radar sensor. In particular, this results in better Doppler resolution and a higher signal-to-noise ratio when evaluating the at least one radar sensor
- the at least one radar sensor can each be an FMCW radar sensor and / or a JSFMCW radar sensor. These advantageous sensor types can thus also be used to implement the present
- executing a corresponding method for evaluating at least one radar sensor also creates the advantages already described above.
- the method for evaluating at least one radar sensor can be developed without any problems so that the advantages of the above-described embodiments of evaluation devices and radar devices are brought about.
- Fig. 2 is a schematic representation of an embodiment of the
- La to lc show functional diagrams for explaining an embodiment of the method for evaluating at least one radar sensor.
- the method described below can be carried out for evaluating a large number of radar sensors.
- a single radar sensor is evaluated using the method described below.
- the respective radar sensor is preferably used to determine information relating to at least one partial environment of the radar sensor.
- the respective radar sensor can e.g. Be part of a monitoring system and / or part of a vehicle control system.
- the radar sensor is, for example, an FMCW radar sensor (Frequency Modulated Continuous Wave Radar Sensor), in particular a JSFMCW radar sensor (Joint Sampling Frequency Modulated Continuous Wave Radar Sensor).
- FMCW radar sensor Frequency Modulated Continuous Wave Radar Sensor
- JSFMCW radar sensor Joint Sampling Frequency Modulated Continuous Wave Radar Sensor
- the radar sensor can also be an OFDM radar sensor (Orthogonal Frequency-Division Multiplexing Radar Sensor, orthogonal frequency division multiplexing radar sensor) or a PN radar sensor (pseudo-random noise radar sensor).
- the radar sensor transmits radar signals 12 during its measurement cycles 10, each with a measurement cycle time / measurement cycle duration At m .
- the radar sensor receives radar signals 14 reflected from its surroundings during its measurement cycles 10 and outputs signals received as the measurement signals corresponding to the received reflected radar signals 14.
- the respective coordinate system has the time axis t as the abscissa, while its ordinate shows time-dependent frequencies f (t) of the radar signals 12 emitted by the radar sensor and the radar signals 14 reflected by its surroundings.
- the radar sensor is designed to carry out chirp sequence modulation (chirp sequence modulation), so that during a single measurement cycle 10 with the
- Measurement cycle time At m a plurality of chirps 16, preferably at least 100 chirps 16, are performed.
- the measurement cycle time At m is usually between 1 ms (milliseconds) to 40 ms (milliseconds).
- the measurement cycle time At m can be, for example, 20 ms (milliseconds).
- the radar sensor remains inactive for a predetermined pause time / pause duration At b .
- the radar sensor remains inactive for a predetermined pause time / pause duration At b .
- the pause time At b is selected such that the radar sensor heats up the component due to the 10 between two subsequent measurement cycles
- the pause time At b is prevented.
- the pause time At b can be, for example, between 5 ms (milliseconds) and 100 ms (milliseconds).
- a sum of the measuring cycle time At m and the pause time At b gives one
- Total cycle time / total cycle time DT A quotient of the measurement cycle time At m divided by the total cycle time DT is often referred to as a duty cycle.
- the measurement signals output by the radar sensor preferably reflect frequency differences between the radar signals 12 emitted by the radar sensor and the radar signals 14 reflected by its surroundings. These frequency differences are made up of a distance-dependent component and one
- the distance-dependent portion indicates the respective distance from the radar sensor at least one object of the surroundings reflecting the transmitted radar signals 12.
- the proportion dependent on the relative speed indicates with which one
- the at least one object moves in relation to the radar sensor.
- the measurement signals of the radar sensor are evaluated by means of the method described below, wherein in particular a Fourier transformation is carried out using measurement signals from at least two different measurement cycles 10 and / or using evaluation signals derived from the measurement signals from at least two different measurement cycles 10. This is explained in more detail below:
- a Fourier transformation 18 is first carried out for each chirp 16 of at least two different measurement cycles 10 with respect to the baseband frequency f ⁇ .
- a plurality of Fourier series 20 are defined for each measurement cycle 10 of the at least two different measurement cycles 10.
- a total number of the defined Fourier rows 20 per measurement cycle 10 of the at least two different measurement cycles 10 thus corresponds to a total number of chirps 16 per measurement cycle 10.
- the Fourier transforms 18 with respect to the baseband frequency f ß can also be called fast Fourier transforms 18 (Fast Fourier transform,
- the Fourier rows 20 determined by means of the fast Fourier transforms 18 all have the same total number of bins.
- the Fourier transformations 18 with respect to the baseband frequency f ⁇ results in a “clamping of a first dimension f ⁇ ” with respect to the respective distance of the at least one reflecting object in the vicinity of the
- the at least one reflecting object in the vicinity of the radar sensor each causes a peak PI in the defined Fourier rows 20, although peaks PI of objects at the same distance from the radar sensor can overlap despite their different relative speeds.
- a further Fourier transformation 22 with respect to a Doppler frequency ⁇ D is carried out for each measuring cycle 10 of the at least two different measuring cycles 10 using the plurality of Fourier rows 20 defined for the respective measuring cycle 10.
- This further Fourier transformation 22 can also be described as a group of one Fourier transformation 22 for each bin of the plurality of Fourier rows 20 of the respective measuring cycle 10. In this way, a two-dimensional Fourier array 24 is defined for the respective measuring cycle 10.
- a first dimension f ß of the two-dimensional Fourier array 24 defined in this way is the respective distance of the at least one reflecting object in the vicinity of the radar sensor, while a second dimension f ß of the two-dimensional Fourier array 24 is the relative speed of the at least one reproduces a reflective object in the vicinity of the radar sensor.
- the two-dimensional Fourier array 24 defined for each measurement cycle 10 can also be referred to as a 2D spectrum of the respective measurement cycle 10.
- the at least one reflecting object in the vicinity of the radar sensor also causes a peak P2 in the two-dimensional Fourier array 24. Superpositions of peaks P2 in the two-dimensional Fourier array 24 can be eliminated using the method step described below:
- the functional diagram of FIG. 1c shows the Fourier transformation 26, which is carried out using the two-dimensional Fourier arrays 24 derived from the measurement signals from at least two different measurement cycles 10.
- the Fourier transformation 26 is carried out with respect to a quantity f 3 relevant to the Doppler effect, a fast Fourier transformation (FFT) preferably being carried out for each bin of the two-dimensional Fourier arrays 24.
- FFT fast Fourier transformation
- a three-dimensional Fourier matrix 28, or a so-called 3D FFT is obtained for a certain number of evaluated measurement cycles 10.
- the Fourier transformation 26 thus extends the previously defined two-dimensional Fourier arrays 24 by a third dimension with regard to the Doppler effect relevant size f3.
- the third dimension can be calculated for any possible relative speed. Depending on the dimensioning of the radar parameters, it can be advantageous to take into account the changing distance of the target via the measurements.
- the third dimension is preferably spanned for each bin of the two-dimensional Fourier arrays 24.
- a number of measurement cycles 10, from the two-dimensional Fourier arrays 24 of which the three-dimensional Fourier matrix 28 is determined, can be between 2 and 15, for example.
- the number of measurement cycles 10 evaluated to determine the three-dimensional Fourier matrix 28 is preferably between 5 and 10.
- the three-dimensional Fourier matrix 28 Since the data for creating the three-dimensional Fourier matrix 28 come from at least two different measurement cycles 10, the three-dimensional Fourier matrix 28 enables observation of the at least one reflecting object in the vicinity of the radar sensor over a so-called integration time T to tai, which extends from the beginning of the earliest of the at least two different measurement cycles 10 to the end of the last of the at least two different measurement cycles 10.
- the integration time Ttotai is thus significantly longer than the measuring cycle time At m or
- Total cycle time DT The method described here thus permits “uninterrupted observation” of the at least one reflecting object in the vicinity of the radar sensor for a period of time equal to the integration time Ttotai, without the radar sensor having to carry out measurements for the entire integration time T to tai. This allows the radar sensor to operate during the
- Integration time T to tai is at least once inactive for the pause time At b , while the three-dimensional Fourier matrix 28 nonetheless displays information about the at least one reflecting object in the vicinity of the radar sensor as if the radar sensor continuously during the entire integration time T to tai would take measurements.
- the integration time T to tai can easily be chosen so long that with an uninterrupted
- the so-called third dimension with respect to the size F 3 relevant to the Doppler effect ensures an improved ability to separate multiple targets based on their differences in the third dimension, and thus also an increased Doppler separability.
- the at least one reflecting object in the vicinity of the radar sensor also causes a peak P3 in the three-dimensional Fourier matrix 28, whereby a superimposition of peaks P3 of different objects cannot / hardly occur.
- Break time At b can cool down so long that overheating of the
- Radar sensor is not to be feared.
- the three-dimensional Fourier matrix 28 can also be determined by means of a “sliding discrete Fourier transformation” (sliding DFT). For this purpose, after each measurement cycle 10, the measurement values of the "oldest measurement cycle 10" can be replaced by a previously defined three-dimensional Fourier matrix 28 by the measurement values of the "latest measurement cycle 10", possibly using a phase term for correction. In this way, a computing time for determining the three-dimensional Fourier matrix 28 can be significantly reduced. In order to reduce the amount of computation, the third dimension of the three-dimensional Fourier matrix 28 can also be determined only for the relative speeds that are considered to be particularly relevant.
